The Lego House singer dated Ellie last summer, with the blonde babe strongly rumoured to have kissed the 1D heartthrob at V Festival - despite Ed and Goulding later spotted holidng hands at the 2013 MTV VMAs the following week.

On LP tune Don't, Sheeran claims his then-girlfriend cheated on him with a pal in the same hotel they were all staying at, while he was downstairs.

Lyrics to the song include: “I never saw him as a threat, ’til you ­disappeared with him to have sex,” and “If I show courtesy and respect to someone, I expect to receive it.

“When we’re in the same hotel, and I’m downstairs at my party and you’re upstairs doing that, that’s disrespectful.”

Despite Ed not naming Goulding or Horan on the song, he is quoted by The Mirror as saying: "The last album was more young and dewy-eyed and innocent.

“I’ve still got very nice songs on this record but some of them are bitey. The story in Don’t is 100% true. I could have gotten nastier – there was more s*** that I didn’t put in."

He continued: "I was seeing someone for a bit, and then they ended up physically involved with one of my friends in the same hotel that we were staying in, while I was downstairs. And I feel like: ‘Treat people how you want to be treated’.”

Despite the claims, Ellie denied being romantically involved with both Ed and Niall, while Sheeran claimed: "It was going on. And now it’s not.”

A rep for Ed is yet to comment on the reports, while the red-haired singer previously told Billboard: "If you date a songwriter, be prepared to have songs written about you.

“If you do nice things, you’ll have nice songs. And if you do f*****-up things, you’ll get a horrible song.”

Meanwhile, Sheeran has revealed the tracklist for x on Instagram, with the record available worldwide from June 23.
